Randomized Controlled Trial Multicenter Study
Single-entity hydrocodone extended-release capsules in opioid-tolerant subjects with moderate-to-severe chronic low back pain: a randomized double-blind, placebo-controlled study.
A single-agent, extended-release formulation of hydrocodone (HC) has been developed for treatment of chronic moderate-to-severe pain. This study was designed to examine the safety and efficacy of HC extended release in opioid-experienced adults with moderate-to-severe chronic low back pain (CLBP). ⋯ Extended-release HC is well tolerated and effective, without acetaminophen-associated risks of liver toxicity, for treatment of CLBP.

Randomized Controlled Trial Multicenter Study
A randomized controlled trial of single point acupuncture in primary dysmenorrhea.
Acupuncture is often used for primary dysmenorrhea. But there is no convincing evidence due to low methodological quality. We aim to assess immediate effect of acupuncture at specific acupoint compared with unrelated acupoint and nonacupoint on primary dysmenorrhea. ⋯ Specific acupoint acupuncture produced a statistically, but not clinically, significant effect compared with unrelated acupoint and nonacupoint acupuncture in primary dysmenorrhea patients. Future studies should focus on effects of multiple points acupuncture on primary dysmenorrhea.
